Solvent Red 197 Description
Solvent Red 197, CAS No. 52372-39-1, is an organic solvent dye used for coloring a range of polymers, plastics and solvent-compatible industrial materials. It has the molecular formula C23H19N5O and a molecular weight of approximately 381.44 g/mol. Public technical data describe the material as a solid powder or crystal, with an orange-brown to dark red appearance depending on the specification and test method. TCI reports a maximum absorption wavelength of approximately 544 nm in toluene, while other industrial dye suppliers describe it as a bright or fluorescent red colorant.
From a purchasing perspective, Solvent Red 197 for plastics is mainly interesting when the final product needs a strong red shade together with good compatibility with the selected polymer system. Commercial technical information lists applications in PS, HIPS, ABS, PC, PMMA, SAN, AS, PET and other polymer materials, while other suppliers also describe applications in synthetic fibers, rubber, waxes, oils, lubricants, coatings and printing inks.
The material is especially relevant to manufacturers working with plastic colorants, polymer colorants and industrial dyes. In practical production, buyers normally evaluate more than the color itself. Tinting strength, dispersion or dissolution behavior, shade consistency, thermal stability, light resistance and compatibility with the resin can all influence the final result. Published technical data for Solvent Red 197 report heat-resistance values in the range of approximately 270–300°C, depending on the test system and supplier specification, so customers should confirm the actual grade against their own processing temperature and resin before bulk production.
For manufacturers purchasing Solvent Red 197 CAS 52372-39-1, this makes pre-production testing important. A small sample can be compared with the customer’s existing color standard before a larger order is scheduled, particularly for transparent or translucent plastics where even a relatively small shade difference can be visible in the finished product.

Why Source Solvent Red 197 from Zhishang Bio?
For industrial buyers, the value of a Solvent Red 197 supplier is not only the quoted price per kilogram. A more practical question is whether the supplier can provide the same product specification repeatedly and communicate clearly about documentation, packaging, production scheduling and shipment.
Zhishang Bio supplies dyes and pigments, chemical raw materials and specialty chemical products to international customers. For Solvent Red 197, our supply process is designed around product identification, specification confirmation, sample evaluation and batch-based quality control before commercial shipment. Customers can confirm the required CAS number, specification, quantity, packaging and destination before the order is finalized.
Our production and quality-control process focuses on maintaining a consistent product profile from raw-material preparation through synthesis, purification, drying and final packaging. The exact production parameters are controlled according to the applicable product specification rather than using a one-size-fits-all process. For buyers using Solvent Red 197 in ABS, PS, PMMA, PC or other engineering plastics, this approach helps make laboratory evaluation and subsequent commercial procurement more straightforward.
Zhishang Bio also maintains production and warehouse coordination for regular orders. Stock availability and production capacity are confirmed according to the current warehouse position, production schedule and order quantity, rather than publishing an unsupported fixed inventory figure. This allows customers to receive a realistic quotation and delivery schedule before placing a purchase order.
For repeat buyers, the purchasing process can be arranged around the customer’s normal consumption cycle. A forecast quantity can be discussed in advance, allowing production and packaging to be planned before the next shipment is required. This is particularly useful for customers who purchase industrial dyes or plastic colorants in recurring batches and need a stable supply channel.
Supply Plan and Delivery Schedule
1. Sample Stage
Customers can begin with a laboratory or production-trial sample of Solvent Red 197. The recommended evaluation should include shade, color strength, compatibility with the target polymer, processing temperature and final-product appearance.
2. Specification Confirmation
Before a bulk order, Zhishang Bio can confirm the product name, CAS 52372-39-1, specification, quantity, packaging, required documents and shipping destination. Customers with an existing internal standard can also provide their target requirements for comparison.
3. Production or Stock Allocation
If the required quantity is available in current stock, the order can move directly to quality checking, packaging and shipment preparation. For quantities requiring production, the delivery schedule is arranged according to the production plan and confirmed order quantity.
4. Shipment
Depending on the destination and order size, sea freight, air freight or other suitable international transportation can be considered. Bulk industrial dye orders are normally more suitable for ocean transportation, while samples and smaller urgent quantities may use express or air transportation.
