Methylene blue is a phenothiazine dye traded as the chloride salt. The table below sets each catalogue parameter against the practical conclusion it forces on classification, shelf conditions, transport and records.

Goods-in control compares three documents before a shelf position is assigned: the waybill, the order and the certificate. A grade designation that differs from the one ordered is treated as a discrepancy, because grades of this dye carry different assay ranges.

Segregation is written on the shelf label as well as in the register, so that the arrangement survives a change of storekeeper. Spillage control matters more here than for most solids, since a stain on a shelf or a balance pan is a persistent contamination route.<\/p>\n\n\n\n

For any movement the primary container goes into a rigid outer box with absorbent filler, and copies of the certificate and the safety data sheet accompany the transport note. The receiving store repeats the complete identity check and opens its own stock card.<\/p>\n\n\n\n

Periodic inspection covers caking, seal damage and staining inside the secondary packaging. The stock card is closed by a transfer, a waste protocol or an exhaustion entry, and the archived certificate keeps the lot traceable afterwards.<\/p>\n\n\n\n
