1H-Naphtho[2,1-b][1,4]thiazin-2(3H)-one CAS 136928-66-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 215.27 g/mol gives 1H-Naphtho[2,1-b][1,4]thiazin-2(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1H-Naphtho[2,1-b][1,4]thiazin-2(3H)-one (CAS 136928-66-0) is a high-purity analytical reference standard with the molecular formula C12H9NOS and a molecular weight of 215.27 g/mol.

Structurally, 1H-Naphtho[2,1-b][1,4]thiazin-2(3H)-one (C12H9NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 215.27 g/mol, it falls into the medium-molecular-weight range. 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), 1H-Naphtho[2,1-b][1,4]thiazin-2(3H)-one 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.
