Ethyl 2-(2-chloroacetamido)-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate CAS 610274-65-2

Description

Ethyl 2-(2-chloroacetamido)-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate (CAS 610274-65-2), molecular formula C17H18ClNO3S and molecular weight 351.85 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-(2-chloroacetamido)-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 351.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Ethyl 2-(2-chloroacetamido)-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
