3,4-dihydro-2H-1,4-benzothiazine 1-oxide CAS 1006482-49-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-dihydro-2H-1,4-benzothiazine 1-oxide.

CATO supplies 3,4-dihydro-2H-1,4-benzothiazine 1-oxide (CAS 1006482-49-0), a certified reference material (molecular formula C8H9NOS, MW 167.23 g/mol) for analytical method development and quality control.

The molecular framework of 3,4-dihydro-2H-1,4-benzothiazine 1-oxide (C8H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3,4-dihydro-2H-1,4-benzothiazine 1-oxide 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.
