Acid Orange 7 Description
Acid Orange 7, identified by CAS No. 633-96-5 and C.I. 15510, is a water-soluble acid dye belonging to the azo dye family. It is also known as Orange II, 2-Naphthol Orange, and Gold Orange. Public chemical databases report the molecular formula as C16H11N2NaO4S and the molecular weight as approximately 350.32 g/mol. The product is generally supplied as an orange, orange-red, or golden-orange powder, with the exact appearance depending on product grade and manufacturing specification.
For buyers looking for an Acid Orange 7 supplier, the most important point is not simply the color of the powder. The material is valued for its water solubility and its suitability for acid-dyeing systems. Commercial and technical sources list textile dyeing, leather dyeing and paper coloration among its industrial uses. Historical technical literature also documents applications in leather, paper coatings, printing and selected non-textile staining systems.
In textile processing, Acid Orange 7 for textile dyeing is relevant to acid-dye systems used with compatible fibers, particularly where an orange or golden-orange shade is required. For a production buyer, however, shade alone is rarely enough to approve a new material. Important evaluation points include dye content, water solubility, shade consistency, color strength, filtration behavior, batch-to-batch consistency and compatibility with the customer’s existing formulation or dyeing process.
This is why sample testing should normally be completed before a bulk order. A laboratory trial allows the buyer to compare the incoming material with an existing reference standard and determine whether the product delivers the required shade and process behavior under the customer’s actual conditions.
The product is also relevant to the wider industrial dyes and colorants market. Depending on formulation and local regulatory requirements, Acid Orange 7 can be considered for applications involving paper colorants, leather dyes, printing inks and other water-based coloring systems. The exact suitability should always be confirmed against the customer’s formulation, end use and applicable regulations rather than assuming that one grade is suitable for every application.

Why Choose Zhishang Bio?
When purchasing Acid Orange 7 CAS 633-96-5 in commercial quantities, procurement teams usually care about three things: consistent specifications, predictable supply and clear communication. A competitive price is useful, but it does not compensate for a batch that behaves differently during production.
Zhishang Bio focuses on the international supply of dyes and pigments, chemical raw materials and specialty chemicals. For Acid Orange 7, our approach is to confirm the customer’s required specification, application, quantity and packaging before shipment, so the commercial order is based on an agreed product standard rather than a generic product name alone.
Production is supported by process control and laboratory testing. The manufacturing workflow can involve raw-material preparation, synthesis, purification, drying and final product inspection, with the exact process parameters managed according to the applicable product specification. For buyers of Acid Orange 7 industrial dye, this is particularly important because relatively small differences in product composition can affect shade strength, dissolution behavior and downstream processing.
Our laboratory support also gives customers the option to evaluate a sample before committing to a larger order. This is useful for textile mills, leather processors, paper manufacturers and distributors who already have an internal color reference and need to compare a new supplier against their existing material.
