Ethyl 2-amino-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate CAS 350997-35-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-amino-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate.

Ethyl 2-amino-5-methyl-4-(4-methylphenyl)thiophene-3-carboxylate (CAS 350997-35-2) is a high-purity analytical reference standard with the molecular formula C15H17NO2S and a molecular weight of 275.37 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-amino-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 275.37 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-amino-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.
