Why ≥99% by HPLC is stated with its method
Purity here is a measured figure paired with the method that produced it: ≥99% by HPLC. Identity is confirmed separately by mass spectrometry. A lot-specific certificate of analysis is available for download, so the figures on the page can be matched to the lot in hand.
How the 5 mg powder ships and stores
The lyophilized powder should be stored sealed at -20 °C, protected from light and moisture. It ships at ambient temperature with desiccant, packed in an insulated mailer. Orders leave Richmond, BC.
Who the 5 mg vial suits in the lab
This listing is a single vial of 5 mg, not a multi-vial pack, and no bacteriostatic water or vials are included with it. It is sold to laboratories and qualified researchers for research use only. Lot numbers on the vial correspond to the downloadable certificate of analysis for traceability in a purchasing record.
Quantity per vial
Each unit contains 5 mg of TB-500 as a lyophilized powder. The 0.05 kg figure is the courier's packed weight, not the net content.
Identity data
Molecular formula C38H68N10O14, molecular weight 889.0 g/mol and CAS 77591-33-4 are stated for record keeping. Identity is confirmed by mass spectrometry.
Documentation
A certificate of analysis is issued per lot and can be downloaded. It states identity, purity and test method.
Packaging
Shipments travel in an insulated mailer with desiccant, outer dimensions 8×8×6 cm. Tracking is provided from Richmond, BC.
Common questions
