Chemical Structure

tert-butyl 2'-chloro-4',5'-dihydrospiro[piperidine-4,7'-thieno[2,3-c]pyran]-1-carboxylate CAS 1307248-45-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-butyl 2'-chloro-4',5'-dihydrospiro[piperidine-4,7'-thieno[2,3-c]pyran]-1-carboxylate.

CATO supplies tert-butyl 2'-chloro-4',5'-dihydrospiro[piperidine-4,7'-thieno[2,3-c]pyran]-1-carboxylate (CAS 1307248-45-8), a certified reference material (molecular formula C16H26ClNO3S, MW 347.90 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, tert-butyl 2'-chloro-4',5'-dihydrospiro[piperidine-4,7'-thieno[2,3-c]pyran]-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), tert-butyl 2'-chloro-4',5'-dihydrospiro[piperidine-4,7'-thieno[2,3-c]pyran]-1-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.
