The analytical panel

Seven analytical categories describe the supported panel. Consult the lot’s certificate for the results and methods actually reported.

• Identity, by mass

  Method: High-resolution mass spectrometry (ESI / time-of-flight)

  Checks whether the measured intact mass matches the expected mass; a match alone does not establish the exact sequence.

• Purity, by HPLC area percent

  Method: Reversed-phase HPLC, UV detection at 210 to 220 nm

  Of everything the detector sees, what fraction of the signal area is the chemical sequence you ordered versus look-alike by-products of making it.

• Sterility

  Method: USP <71> 14-day culture, or validated rapid PCR; the certificate names the lot’s panel

  Confirms no viable microorganisms ride in the material, so the vial is not a hidden culture of bacteria or fungi.

• Bacterial endotoxins, by LAL

  Method: Kinetic chromogenic LAL (USP 85)

  Checks for traces of dead gram-negative bacterial debris, a heat-stable immune trigger that can light up assays all by itself.

• Heavy metals, by ICP-MS

  Method: Inductively coupled plasma mass spectrometry (USP 232 / 233, ICH Q3D)

  Measures toxic metals (lead, arsenic, cadmium, mercury) and leftover catalyst (palladium) down to parts per billion.

• Residual solvents, by headspace GC

  Method: Headspace gas chromatography (USP 467, ICH Q3C)

  Finds leftover manufacturing solvents (acetonitrile, dichloromethane, methanol) that are toxic, can interfere with assays, and are dead weight, not chemical sequence.

• Net content, by mass

  Method: Gravimetric fill on a calibrated microbalance (USP 697 / 755)

  The actual weighed mass of chemical sequence in the vial, the number you divide your volume into to get the real concentration.

Record and verification details

The released certificate identifies the method, record reference, and sale window for a lot without exposing a public lot list.

How our inventory is stored

Every chemical sequence and residue in our inventory is held at −86 °C until the day it ships.

Each is kept in ultra-low-temperature freezers at −123 °F. Cold slows the chemical reactions, such as oxidation and deamidation, that wear a chemical sequence down over time.

Stated storage setpoint. Not a reading from any lot.

Reference temperatures are laboratory conventions.

A certificate records a lot at the moment it was tested. What happens to the vial after that is storage. This is our storage condition, stated by us. It is not a figure measured on any certificate. The storage temperature covers the time before dispatch. Parcels are not refrigerated in transit.

Why storage temperature matters, in the stability course

Recalls

If a lot needs to be pulled, we recall proactively by sale window, the interval between a lot’s synthesis and expiry dates, so affected orders are identified automatically.

Agentic and programmatic verification

Autonomous agents, IDEs, and analytical systems can query and verify sequence purity, batch parameters, and COA interpretation through the public read endpoints, whose Model Context Protocol tool definitions are published at /ai/mcp/tools.json.
