CBL (cannabicyclol) is a photochemical rearrangement product of CBC: light cyclises CBC into CBL. It shares CBC's formula, C21H30O2, so it cannot be told from CBC by mass alone, only by chromatography or structural identity. Peregrine sells it as a research isolate for reference libraries and impurity mapping, not as a finished consumer cannabinoid.

Buying guide
Bulk CBL isolate: what it is and how to buy it
CBL isolate is cannabicyclol (CAS 21366-63-2, C21H30O2), the photochemical rearrangement product of CBC, at ≥99.9%. It is not made by a plant enzyme; it forms when CBC is exposed to light, which is why it appears in aged material and in stability studies. Peregrine offers it as a research-grade isolate for analytical libraries and impurity mapping. Typical demand is 5 g to 1 kg; larger tiers stay Coming Soon until a campaign is scheduled. A per-lot COA ships with the material.
Why would a lab buy CBL isolate?
Because CBL is what CBC becomes under light. Any product containing CBC will show CBL over time, so stability programmes, impurity mapping and method validation need an identified CBL reference to name the peak. It shares CBC's formula (C21H30O2) but has a distinct cyclised structure, so it is resolved chromatographically and confirmed by identity, not assumed.
How is CBL isolate produced?
Typically by controlled photochemical conversion of CBC followed by chromatographic purification and crystallisation. Because it is produced on demand rather than harvested, campaign sizes are small and kilogram tiers open only against a written campaign.
What should a COA for CBL isolate show?
Identity and assay for the named cannabinoid, at minimum. Identity is HPLC against a qualified reference standard; when a primary standard is on allocation, Peregrine discloses NMR or LC-MS identity on the COA rather than implying HPLC. Assay is reported as percent w/w of CBL, and a lot is listed as Available only after both clear.
Residual-solvent (ICH Q3C classes as applicable to the process), heavy-metal and pesticide panels ship with the lot pack when you request them on the inquiry. Appearance, water activity, storage condition and origin are lot-specific and printed on the COA, not on this page. Identity matters more than usual here: CBL and CBC share a formula, so a mass alone does not distinguish them.

How should CBL isolate be stored?
Ambient, dry and dark unless the COA says otherwise. CBL is the more light-stable end of the CBC → CBL conversion, but the container should still be kept closed and out of light.
How do you buy bulk CBL isolate from Peregrine?
Pick a mass on this page, add the destination jurisdiction, and send the inquiry. A person answers with a quote in one business day. Today every CBL isolate mass tier is Coming Soon: production is campaign-based and a tier opens only after the lot clears identity and assay. Send the inquiry anyway — it is how you are told when the campaign is scheduled, and the 5 g research cut is the first tier to open. Typical commercial demand is 5 g to 1 kg.
Every mass tier shows one of three states: Available (identity and assay have cleared), Contact for pricing (a human quotes the campaign), or Coming Soon (we cannot take the order until the lot exists). Incoterms, carrier and pickup window are on the quote. For multi-product requests use the procurement form on /quote.

Questions about CBL
What is CBL made from?
CBC. Light rearranges cannabichromene into cannabicyclol; there is no CBL synthase in the plant.
Is CBL psychoactive or used in consumer products?
Peregrine sells it as a research isolate for analytical and stability work and does not describe consumer uses.
What purity is CBL isolate?
≥99.9% cannabicyclol on the lot COA, identity-confirmed.
Why is CBL only available in small masses?
It is produced on demand for research; typical demand is 5 g to 1 kg, and tiers open per campaign.
Does CBL have the same formula as CBC?
Yes, C21H30O2 — but a different structure. That is why identity, not mass, confirms it.
Why offer CBL?
So an analytical method can name the CBL peak with a confirmed reference. Most orders are between 5 g and 1 kg.
