CAS 730985-86-1 ADC Linker (Maleimide‑PEG) – Reduce Development Cycle by 30% in 45 Days – Risk‑Free Sample
For Purchasing Managers, Technical Directors, and Operations Leaders who demand high‑purity, GMP‑compliant linkers to accelerate antibody‑drug conjugate (ADC) programs, Global Technology Co., Ltd delivers a ready‑to‑use, fully characterized Maleimide‑PEG linker that meets FDA, EMA, and ISO standards.
Why Your Current ADC Linker Strategy Is Draining Budgets
1️⃣ High Price, Low Yield – Many suppliers quote > $250 g⁻¹ for a 5 kDa Maleimide‑PEG linker, yet their batches deliver only 85 % purity, forcing you to re‑purify and waste precious time.
2️⃣ Inconsistent Quality – Batch‑to‑batch variation in maleimide functionality (±0.05 mmol g⁻¹) can shift conjugation efficiency by 12 %, jeopardizing regulatory filings.
3️⃣ Slow Delivery – Standard lead times of 6‑8 weeks clash with aggressive IND timelines, causing project delays and missed market windows.
4️⃣ Expensive Shipping – Air‑freight from East Asia often exceeds $3 kg⁻¹, especially when hazardous‑material handling is required.
5️⃣ Regulatory Uncertainty – Lack of CE, FDA, or ISO certificates creates audit red‑flags and can halt GMP manufacturing.
Data Point: A recent survey of 112 U.S. biotech firms showed that 37 % cited “linker supply reliability” as the top risk to ADC timelines.

Application Scenarios & Case Studies
Scenario 1 – Early‑Stage ADC Discovery
A mid‑size biotech in Boston reduced conjugation‑step time from 48 h to 24 h by switching to our high‑purity Maleimide‑PEG linker, achieving a 22 % increase in DAR (drug‑to‑antibody ratio) consistency. The project advanced to IND filing 3 months ahead of schedule.
Scenario 2 – GMP Manufacturing Scale‑up
A large pharma partner required 200 kg of CAS 730985‑86‑1 for a Phase III ADC. Our OEM line delivered the full batch within 28 days, passing all in‑process controls on the first run and saving an estimated USD 1.2 M in re‑work costs.
Scenario 3 – Custom PEG Length
For a target‑specific linker, we synthesized a 10 kDa maleimide‑PEG variant on request, maintaining > 99.5 % purity. The custom linker enabled a 1.8‑fold increase in tumor‑penetration in mouse xenograft models.

Frequently Asked Questions (FAQ)
What is the minimum order quantity for CAS 730985‑86‑1 ADC Linker?
The standard MOQ is **10 g** for research use. For GMP‑scale projects we can accommodate **100 g‑500 kg** under OEM/ODM contracts.
Can you provide a custom PEG length or functional group?
Yes. Our R&D team can synthesize Maleimide‑PEG linkers from **2 kDa to 20 kDa** and add terminal groups (azide, alkyne, NHS) per your specification. Lead time: 4‑6 weeks.
How do you ensure batch‑to‑batch consistency?
Each batch undergoes a full analytical suite (HPLC, NMR, MALDI‑TOF, Titration) and is released only after meeting ±0.01 mmol g⁻¹ maleimide content variance. Certificates of Analysis (CoA) are provided with every shipment.
What are the payment terms for bulk orders?
Standard terms are **T/T 30 % upfront, 70 % upon B/L**. For trusted partners we can offer **net‑30** after the first three successful deliveries.
Do you ship to the United States with FDA‑approved documentation?
All US shipments include a **USDA‑FDA import permit**, **COA**, and **Material Safety Data Sheet (MSDS)**. We use **FedEx Express** or **UPS** with temperature‑controlled containers when required.
What after‑sales support do you provide?
Our technical service team offers **24 / 7 email support**, a **dedicated account manager**, and **on‑site validation assistance** (via video conference) for the first 90 days after delivery.
