What is DAST?

DAST, also known as Diethylaminosulfur Trifluoride, is a reactive fluorinating reagent widely used in organic synthesis, fluorine chemistry, pharmaceutical intermediate development, and other research involving selective fluorination. Its CAS number is 38078-09-0, with the molecular formula C4H10F3NS and molecular weight of 161.19 g/mol.

DAST is a liquid at room temperature and is commonly supplied as a high-purity chemical reagent. It is especially useful when a synthesis route requires the conversion of selected oxygen-containing functional groups into fluorinated structures. For example, DAST can react with alcohols to form alkyl fluorides, while reactions with aldehydes and ketones can be used to introduce gem-difluoro functionality. These properties make DAST CAS 38078-09-0 relevant to research involving fluorinated organic compounds, pharmaceutical intermediates, and specialty chemical synthesis.

From a procurement perspective, DAST is different from ordinary bulk chemical materials. Moisture control, packaging integrity, batch consistency and transportation conditions all matter. The material is moisture-sensitive and reacts with water, so appropriate handling and storage procedures should be followed according to the applicable SDS and product specification.

Typical Applications

  • Organic synthesis: Used as a fluorinating reagent in synthetic chemistry.
  • Alcohol fluorination: Used to convert suitable alcohol functional groups into corresponding fluorinated compounds.
  • Carbonyl fluorination: Can be used with aldehydes and ketones for the preparation of fluorinated products.
  • Pharmaceutical intermediate research: Useful in synthetic routes where fluorine substitution is required.
  • Fluorine-containing compound development: Applied in research and process development involving fluorinated organic molecules.
  • Specialty chemical synthesis: Suitable for laboratories and manufacturers developing fluorinated intermediates and advanced organic molecules.

Superior DAST Series | Reliable Quality & Sufficient Supply

For buyers sourcing DAST CAS 38078-09-0, product identity alone is not enough. The supplier also needs to provide consistent batches, suitable packaging, documentation and a practical supply plan.

Zhishangbio focuses on supplying specialty chemicals, pharmaceutical intermediates, and other chemical raw materials to international buyers. For DAST, our supply process is designed around batch-level quality control and buyer requirements rather than simply quoting a product name and price.

Quality and Production Advantages

 

Our DAST supply program can support buyers with:
  • Batch-based quality control before shipment
  • Product specifications matched with the agreed purchasing requirements
  • COA and SDS documentation available according to the order
  • Moisture-conscious packaging and handling
  • Flexible packaging options for different purchasing volumes
  • Support for sample, development and larger commercial orders
  • Export-oriented packing and shipment coordination
  • Communication with buyers before production, packing and dispatch

For customers developing a new synthesis route, we can also discuss the required purity, packaging size, order quantity and documentation before confirming the quotation. This helps reduce unnecessary changes after the purchase order is issued.

DAST Supply Plan & Delivery Schedule

A reliable DAST supplier should be able to explain what happens after a purchase inquiry. Our standard B2B workflow is designed to keep the process clear from specification review through shipment.
 
Inquiry → Specification Confirmation → COA/Sample Review → Order Confirmation → Stock Allocation or Production → QC Inspection → Packing → Shipment
 
For sample or small-volume orders, availability can normally be checked against current inventory. Larger DAST bulk orders may require production scheduling, particularly when the requested quantity exceeds available warehouse stock.

FAQ

DAST CAS 38078-09-0 is mainly used as a fluorinating reagent in organic synthesis. It can be used in suitable reactions involving alcohols, aldehydes and ketones to prepare fluorinated organic compounds.

The molecular weight of Diethylaminosulfur Trifluoride is 161.19 g/mol. Its molecular formula is C₄H₁₀F₃NS.

DAST is moisture-sensitive and reacts with water. Storage and handling should therefore follow the supplier’s SDS, product specification and applicable chemical safety requirements. Commercial reference data commonly list 2–8°C storage conditions.

For a bulk purchase, buyers should confirm purity, CAS number, batch information, COA, SDS, packaging, MOQ, available quantity, shipping requirements and delivery time. For international orders, it is also useful to confirm the destination and required import documentation before shipment.
