Chemical Structure
Description
The occurrence of Lead(II) sulfide is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Lead(II) sulfide (CAS 1314-87-0) is a high-purity analytical reference standard with the molecular formula H2PbS and a molecular weight of 241.28 g/mol.
Structurally, Lead(II) sulfide (H2PbS) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 241.28 g/mol, it falls into the medium-molecular-weight range.
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), Lead(II) sulfide 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.
