Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 133.17 g/mol gives Carbamothioylmethyl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carbamothioylmethyl acetate (CAS 40235-62-9) is a high-purity analytical reference standard with the molecular formula C4H7NO2S and a molecular weight of 133.17 g/mol.
Structurally, Carbamothioylmethyl acetate (C4H7NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 133.17 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Carbamothioylmethyl acetate 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.
